The excerpt from All summer in a day conveys a tone of joviality and childhood innocence.
Explanation
The text conveys a feeling happiness and innocence through the comparison of the children to roses and so many weeds. The phrase so many exemplifies the easy carelessness of the comparison that one can see through the meanings conveyed by the lines.
The author creates this tone to eventually lead to a somber realization on the impermanence of the summer and how the children are bound to be happy for such a short time.
